Golden Gecko in Pet Store

[Newt]

theres this golden gecko in the pet store here
hes on calci sand ....no humidity,dirty tank
this is a small town pet shop so they only get one or 2 lizards in at a time
leos and water dragons...they had a beardie
but this lil guy had sat n sat
i dont think hes the type anyone wants
cept me
and i know buying from pet stores only makes em get more but i figure he'll be that last golden gecko they get
the ppl are nice there and i can get them to change their gecko tanks
but i still dont think this lil guy will be sold
i saw him eat and hes very active and has a nice golden color, he is missing a toe possibly burnt off by the hot rock
his belly is fat so i figure hes either impacted or just well fed
so ive rambled enuff
what do u all think? and are there any good care sheets for golden geckos?
